I agree ... I think splitting is for maybe when you're with your family. Or just treating your family altogether
Or if you're hosting at your home. IMO the host is to cover everything for the guests.
My friends are always considerate enough to ask "what should I bring? A bottle? Food?" When I'm hosting but I always tell them just bring yourself . Everything is taken care of .. food drink dessert . There should be no requirements or expectations attached to that type of invite IMO.
And they know anytime I'm hosting they about to eat GEWD. I order and plate the food with lots of luv. ☺️☺️
My MLK Jr. Day soul food dinners are quite iconic
